W7020 Radio Module
Features
Description
+ Complete RF solution, compliant with Bluetooth*
specification version 1.0B
The W7020 radio module is a short-range microwave-
frequency radio transceiver for Bluetooth links. It
operates in the globally available 2.4 GHz to 2.5 GHz
ISM band. The radio is based on a bipolar
complementary metal-oxide semiconductor (BiCMOS)
RF integrated circuit. The antenna filter and the RX and
TX baluns are all integrated into the radio subsystem
(see Figure 1).
+ Highly integrated module including RF transceiver IC,
antenna filter, and transmit/receive baluns
+ 0 dBm, typical, output power at 50 Ω
+ 2.7 V operation enabling long battery life
+ 3.2 kHz low-power, idle-mode clock
As illustrated in Figure 2, the radio module requires
only an external antenna connected through a 50 Ω
characteristic impedance line and a 13 MHz crystal or
reference clock signal to enable Bluetooth radio
communication links. It interfaces to a baseband
controller through the serial interface bus and separate
strobe signals to create a complete Bluetooth hardware
solution.
+ Digital receive signal strength indicator (RSSI)
+ Small-outline module ceramic land grid array
(MCLGA) package (9.7 mm x 14.0 mm x 1.6 mm)
+ Evaluation kit available, including W7020 evaluation
board, USB transceiver interface board, and PC
control software
